IMPROVEMENT IN SHUTTLE-MOTIONS FOR LOOMS.

Specification forming part of Letters Patent N 167, 176, dated August31, 1875; application filed January 12, 1875.

To all whom it may concern:

Be .it known that I, CHARLES I. KANE, of Milford, in the county of NewHaven and State of Connecticut, have invented certain new and usefulImprovements in Shuttld-Motions for Looms; and I do hereby declare thatthe following is a full, clear, and exact description of the same,reference being had to the accompanying drawing forming part of thisspecification.

This invention more particularly relates to looms for weaving narrowgoods, and in which a raceway for the shuttle, open both above andbelow, is used.

The invention consists in an open raceway, composed of or provided onits opposite edges with grooved or flanged guide-rollers, for bothdirecting the shuttle in its course and for supporting the same, andwhereby the use of oil or lubricating material to facilitate the run ofthe shuttle, and which is apt to soil the goods,

a transverse vertical section thereof, on the line w 00, looking indirection of the arrow y.

A is the raceway, in which the shuttle B, that should be provided withthe usual bobbin, works. Said raceway is open both above and below, andis composed or provided, on its front and back or opposite edges, of orwith grooved or flanged guide-rollers C, which, by their construction,not only serve to direct the shuttle in the line of the raceway, butalso to support the shuttle, the latter, on its edges, being made to fitthe grooves or flanges of the guide-rollers.

By this construction of the raceway and shuttle to suit, oil orlubricating material to facilitate the run of the shuttle, and which isapt to soil the goods is dispensed with.

The raceway A, shown in the drawing, is of an arc shape or in form of acircle, the plane of which is parallel, or nearly so, with that in whichthe web is woven, and perpendicular to the harness-motion. Said racewayis stationary, for use in combination with a lay or beater, having areciprocating motion, and has its outer edge constructed with anopening, b, wide enough for the free passage of the Warp.

When the raceway is of a curved form, as shown, the shuttle Bis ofcorresponding curvature on its edges, and the same may be constructed,as in my patent hereinbefore referred to, of a thin flat frame. It isvery desirable in fact to have the shuttle as thin as possible,especially at its front edge, to reduce the necessary width of openingthe shed. To this end, and to do away with the crossing of the shuttledrivers or fingers D, and to operate the latter from the front side oftheir center of oscillating motion cl, which is concentric with theraceway, said fingers are made to come up from below to gear alternatelywith opposite ends of the shuttle, thus dispensing with projections onthe bottom of the shuttle for reception of the fingers, and are operatedas follows: The oscillating shuttle-driver or fingercarrier E isconstructed with slotted arms or guides f, which are set inclining totravel over or against a conical stationary grooved cam, G, in front ofthe center of motion d, and with the groove g of which the fingers Dgear, by means of rollers on their faces, to give to said fingers theirnecessary up and down motions for alternate driving connection with an dclearance of the shuttle, as required, as the carrier E is oscillatedfrom d as a center of motion.

I claim- The raceway, composed of or provided, both on its front andback edges, with flanged or grooved guide-rollers, in combination with ashuttle, having its bearing-edges constructed to correspond, wherebysaid shuttle is not only directed but supported by the rollers,substantially as specified.
